Split text by characters, words or paragraphs, with optional overlap.
Use and export
Paste text, load a UTF-8 file or try the sample.
Choose options and select Run. Review the result, counts and any warnings.
Copy or download the result in an available format. Run again after changing inputs.
Methods and limits
Up to 250 chunks, size 1–50,000 units. Overlap must be smaller than the chunk size. Characters are Unicode grapheme clusters, words are whitespace-separated and paragraphs are separated by blank lines. Word/paragraph modes normalize separators. These are not model-token counts. ZIP export contains numbered UTF-8 text files and a manifest.
Private processing
Text and files stay in browser memory and a local worker. No uploads, account access, network lookups or automatic storage. Refreshing clears your work. Input is limited to 500 KB and generated output to 1 MB; processing times out after five seconds. Downloads and clipboard copies contain the output you choose.
